v0.13.12 shipped the async fd_recovery design but a live test on Dune 2 showed Pass 1 sat for 14 minutes with bytes_good=0 — the inner loop iterates (throttled on_progress log fires every 78s) but each iteration evidently takes ~60s instead of the microseconds the design promises on fast-fail. Without trace-level telemetry at the SCSI + Disc::copy boundaries we can't tell where the time goes. This release is instrumentation only — no behavior change. - New dep: tracing 0.1. Per CLAUDE.md, debug/trace logging is allowed in libfreemkv (the no-English rule applies to errors). Consumers wire a tracing subscriber. - SgIoTransport::execute (Linux): trace at every state transition (entry, recovery_swap_ok, recovery_pending, write_ok / write_err, poll_done, timeout_spawn_recovery, scsi_err, read_err, ok). Each event includes opcode + elapsed timing. The bg recovery thread also traces close_ms + open_ms so we can see if the kernel really takes 60s to close+open on a wedged Initio bridge. - Disc::copy: trace at copy_start, outer_loop, region_enter, every 100 inner-loop iterations (iter_progress with pos/region_end/skip_size/ bytes_good/read_ok_count/read_err_count/last_read_ms/copy_elapsed_ms), copy_done. - All trace events use targets `freemkv::scsi` and `freemkv::disc` so consumers can filter by subsystem (e.g. autorip /api/debug?q=freemkv::scsi). Next: run the live test on Dune 2 again, read the autorip JSONL log, diagnose why each iter is slow, fix the actual bug.
